Catching Up with Allen Keeney of Johns Hopkins University

December 7, 2021 | Dan Beaulieu, D.B. Management Group

I have always been fascinated by research labs, especially those tied to major universities. These are the true leaders of innovation and invention and at the very top of the PCB industry. So, when I met Allen Keeney, chief engineer of the Advanced Electrical Fabrication Group at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, I jumped at the chance to talk with him.
